When magnesium carbonate, MgCO2, reacts with nitric acid, HNO3, it forms magnesium nitrate, Mg(NO3)2, and carbonic acid, H2CO3. Carbonic acid then breaks down into water and carbon dioxide. Which two types of reactions take place in this process?

A. synthesis and decomposition

B. single-replacement and combustion

C. double-replacement and decomposition

D. double-replacement and combustion

your formula for magnesium carbonate is wrong, but you've already got the names of all the reactants and products. write the reactions with the formulas, and it should tell you what kind of reactions are taking place. take a look at this question http://openstudy.com/study#/updates/522e7c18e4b0fbf34d63ce02
